HINGE.

Application filed December 30, 1925. Serial No. 78,400.

' tively on ball bearings.

A i'uriher ObJGCt is to provide a hinge con-.

struction which, when formed, will be more securely imbedd'ed in the material of the door and the amb.

A. further object is to ing hinge construction in which the parts are of simple design to reduce the expense of manufacture, few in number and capableof being very readily assembled and disassembled.

The invention is illustrated in the drawings, of which Figure 1 is a horizontal section taken through a door and a amb showing the hinge members in place;

Figure 2 is a vertical section taken on the line 22 of Figure 1;

, Figure 3 is a vertical section taken on the line 33 of Figure 1;

Figure 1 is a side elevation of the hinge;

Figure 5 is a plan view of one of the hinge members in blank form;

Figure 6 is a similar view of the other hinge member in blank form.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the con struction and arrangement of the parts and in the character ofthe materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims.

In its general aspect this invention relates to a hinge in which the hinge plates preferably project into the material of the door and the amb, at-right angles to the surface there-, of, so as to directly aid in bearing theload of the door rather than putting this weight on a few screws.

It is further contemplated to provide the hinge plates on their end portions projecting from the door and the jamb surfaces with ball bearing race casings held together and related in a simple manner so as to reduce the friction in the operation of the hinge members to a minimum.

provide a'ball bear *In the preferred form of the invention shown in the drawings the hinge members are formed as blanks having portions, 10 and 11 in the form of fiat plates pointed as at 12 and 13' to project into a suitable slot or saw cut formed re.-Dectively in the jamb and the door 14 and 15. Adjacent these plates are disposed strips 16 and 17 which are bent up to form tubular members, from the forward portion. of each of which toothed prongs such as 18 and 19 project. These are adapted to be driven into the wood of the door and amb and to lock therewith in order to hold the hingeelements in place. These tubular ancmbers are adapted to fit into bores such as 20 and 21' formed in the door and jamb. adjacent one edge of the saw cuts above mentioned. The hinge elements-are also provided with rearwardly extending plates such as 22 and 28 one of which, 23, is adapted to have its periphery bent up, as shown in F igure 2, to form a flanged, cup-like receptacle to receive ball bearings 24:. The other plate 2 is adapted to have its central portion flanged downward to form a flange such as 25, (see Figure 2) thus providing between the turned up flange on the plate 23 and the downturned flange on the plate 22, a. channel for the reception of the ball bearings. A cover plate 26 is disposed over the two hinge plates and is provided with an aperture alined with an aperture 27 formed in the plate 23 and these apertures receive a headed locking pin 28 which is provided with a head 29 and split prongs 30 and this holds the various plates firmly together.

The rear edges of the strips 16 and 17 are provided with a plurality of spaced ears 31, which when the strips are bent up in tubular form are turned inwardly, as shown in Figures 1 and 2 to partially close the end of the tube and to give it a finished appearance and also to form a surface which can be lightly struck by a hammer or other light tool to drive the hinge elements into place.

In the .operation of assembling the hinge and mounting it on a door and a jamb it 1s to be understood that the strip portions 16 and 17 are rolled up and the extension plate portions 22 and 23 are bent to the proper form as described. The hinge plate 10 is then inserted in the saw cut in the door 15 with the tube 16 projecting into the bore 20 and the prong 18 projecting into the wood of the door. Likewise the hinge element 11 is inserted into the saw cut in the jamb 14:

l U U with the tube 17 rolled up and disposed in the bore 21 with the prongs 19 projecting into the wood of the jamb. With the plate 22 overlying the plate 23 and the balls 24 in position, the cover plate 26 is disposed thereo'ver and the locking pin 28 is put into place to hold the device together.

This hinge construction is therefore extremely simple and cliicient and durable.

What I claim is:

1. 1; device for fastening hinge members and the like to a support which includes a. plate portion, a tubular member on the plate portion, said t ibnlar member and a portion of the plate adapted to be inserted respec tively into a tubular bore and a slot in the support, the outer end of the tubular portion being closed to oller a surface to be struck by a hammer when forcing the device into embedded position within the support.

2. A device for fastening hinge members and the like to a support which includes a plate portion, a tubular member on the plate portion, said tubular member and a portion of the plate adapted to be inserted respectively into a tubular bore and a slot in the support, the outer end of the tubular portion being closed to offer a surface to be struck by a hammer when forcing the device into embedded position within the support, the closed end of the tube being formed by a plurality of spaced inwardly turned tongues integral with the end of the tubular member.

3. A hinge construction which comprises a pair of hinge plates, a portion of one plate being bent up at its-edges to form a cup, and centrally raised to form a boss, a portion of the other plate having a relatively large central opening therein, the material at the edges of the opening being bent down to form a. flange encircling the boss, said flange defining with the flange of the cup, a ball race, a cover plate to be disposed over said plate portions, centrally depressed to fit within the opening in the upper plate, said cover plate and boss having aligned apertures therein .t'or the reception of an interlocking pin for holding the plates together.
